vices now in common use have various drawbacks. They may be diflicult toassemble, or their cost may be excessive. In some instances, the deviceis so constructed that it is ditiicult or impossible to flow or pack theconcrete solidly around the dowel adjacent the joint.

it is therefore an object of my invention to provide a transload devicewhich is inexpensive and is easily fabricated by welding the variousparts together.

Another object is to provide such a device made of two units which canbe easily assembled by telescoping the units together.

Still another object is to provide a transload device which enables theconcrete to flow or be packed solidly around the dowel adjacent thejoint.

These and other objects will be more apparent after referring to thefollowing specification and attached drawings, in which:

Figure 1 is a perspective view of an expansion joint assembly;

. places.

Figure 2 is a transverse section of the expansion joint of Figure 1;

Figure 3 is an enlarged sectional view of a detail;

Figure 4 is an elevation of a detail;

Figure 4A is a view taken on the line IV-A-IV-A of Figure 4; and

Figure 5 is a view similar to Figure 2, but showing a contraction joint1.

Referring more particularly to the drawings the reference numeral 2indicates a pair of concrete slabs having the usual filler member 4therebetween. My device is made of two complementary units which aretelescoped together. Each unit has two longitudinal rods 6 and 8 spacedfrom the filler 4 and connected by rods 10 and 12 which are weldedthereto. Rod 10 is U-shaped with the open end of the U being welded tothe lower wire 6 and the closed part of the, u extending above and beingwelded to the top wire 8, thus providing an opening 14. A dowel 18extends into the opening 14 and is welded to the rods 8 and 10. The rod12 has a vertical portion, the lower end of which is welded to the rod6, and a top portion which formsa clamping device 20. The clampingdevice, as best shown in Figure 4, is provided with a loop 22 forreceiving the free end of the dowel" 18 and a longitudinal portion 24which extends along the rod 8. The free end of the portion 24 has a book26 which is adapted to pass below and extend around the rod 8 to a pointjust below the axis of the rod. The rods 10 and 12 are arrangedalternately with the rods 10 of one unit being opposite the rods 12 ofthe other unit. A plate 28 is welded to each of the dowels 18 on thatside of the tiller 4 adjacent the rod 10. The plates 28 are bent at 30to receive a longitudinal rod 32 which is welded to the plates 28 andextends the length of the joint. As shown in Figure 1, the end of rod 32is bent toward rod 6 to which it is welded and the end of rod 8 is bentdownwardly and welded to the bent portion of rod 32. Holes 34 areprovided in the filler 4 for passage of the dowels, the free ends of thedowels having sleeves 36 telescoped thereover. An expansible filler 38is provided in the sleeve 36 at the outer end thereof.

In assembly, the two units are brought together by passing the free endsof the dowels through the openings 34 into the loops 22. The sleeves 36and fillers 38 are then applied to the dowels and the hook 26 is movedfrom the dotted line position of Figure 4 to the full line position,thus locking the two units together with the plates 28 bearing againstopposite sides of the tiller 4 to hold it in position while concrete ispoured. The plates 28 do not interfere with the flow or packing of theconcrete around the dowels adjacent the joint, thus making it possibleto provide dense concrete at the most critical The device functions inthe usual manner as the concrete slabs 2 expand and contract.

Figure 5 shows my device as applied to a contraction joint. The onlydifferences in the two joints are the omission of the sleeves 36 andfiller 38 in the contraction joint and the substitution of a steelseparating plateor filler 40 for the expansible filler 4.

While two embodiments of my invention have been shown and described itwill be apparent that other adaptations and modifications may be madewithout departing from the scope of the following claims.
